Ologies with Alie Ward Alie Ward

How long can we live? How much of aging is genetics vs. environment? How old are your cells? What can we learn from the world’s oldest people? World-renowned aging expert and biogerontologist Dr. Caleb "Tuck" Finch takes a quick break from his prolific research at USC to answer Alie's sometimes basic questions about everything from molecules to Blue Zones.

Weird little mouths! Hairy skin tubes! Demon nematodes! Antarctic explorer and Nematologist Dr. Holly Bik charms us into loving deep sea (benthopelagic) worms in a way you never thought possible. We also cover tiny worm brains, the smell of Antarctic mud, first-generation Ph.Ds, the research workhorse C. Elegans, deep sea mining machines, moisturizers, submersibles and more with a worm lady who has literally traveled to the ends of the Earth to ask: what’s in that mud? We love her.

Sweet! Salty! Umami? What’s up with MSG? Why do you like your coffee black? Come down to flavortown and let’s talk tongues. Gustologist Dr. Gary Beauchamp is a chemosensory scientist and an expert in taste. We chat about tastebud flim-flam, celebrity grade hot wings, MSG research, excitotoxins, weaning off sugar, the worst soup on the market, what countries have salt restrictions, why you lost your taste with Covid, how much taste is smell, artificial sweeteners, acquiring a taste for foods, and how a sweet tooth may affect your booze consumption. Delicious facts, served up hot.

Dr. Mack returns with a new introduction and updates on… listener questions! The universe, dimensions, asteroid bags and cosmic vertigo with the amazing Astro Katie, AKA Dr. Katie Mack. Part 1 was a primer on all things cosmological, from particle physics to black holes, so listen to that first then hop to this episode to get all your questions answered.

The Red Planet. A mysterious dusty orb millions of miles away. Our emergency escape bunker. Alie sits down with Dr. Jennifer Buz to talk about what Mars’s DEEEEAL is, why we send rovers there, the poetry of the moon Phobos, Martian sunsets and whether we could landscape Mars to look like a golf course. Jennifer is maybe the chillest areologist on this planet and an absolute gem.

Stars. Black holes. THE GAWDANG UNIVERSE. Astrophysicist and cosmologist Katie Mack (@astrokatie) re-introduces us to this 2017 episode along with some bonus updates on astrophysics, her career, and the book she’s published since we last heard from her. Katie also tells us her most embarrassing moments as a cosmologist, debunks some physicist myths and gives us the nuts + bolts of everything form particle physics to gravitational waves and existential mysteries. Walk away with cocktail party comprehension of everything from the itty-bitty quarks that make you to the neutron stars banging together across the cosmos. More than anything, get perspective about your life on this, our little pale blue dot.
